IMPROVEMENT IN BOBBINS IOR SPINNING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, Ornus B. Mensa, of Rhinebeck, in the county of Dutchess, and State of New York, have invented a new and useful Improvement in-Bobbins; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawings, forming apart of this specification, in which- Figure 1 is a view of a spindle, with a bobbin attached, ii -longitudinal section.

Figure 2 is a side view of a bobbin, partially shown in section. v

Figure .3 is an oblique section, taken in the plane of the line x'sr, fig. 2, showing the transverse direction of holes a made for packing.

Figure 4 is a transverse section taken in the plane of the line y y, fig. 2, showing the intersection of the plane by the holes at points equidistant from the centre of the bobbin.

Similar letters of reference indicate like parts.

The object of this invention is to centre a bobbin for spinning wool, cotton, and other fibres upon the spindle, by means of a packing of twine, rubber, or other suitable substance, inserted in holes made through the bobbin obliquely to its line of axis, and intersecting the same transverse plane at points equidistant from the centre of the'bobbin. i p r The wooden bobbin employed by-s'pinners ofcotton and woollen yarns and other fibrous materials, forwinding the cop upon it, requires to be set centrally on the spindle with great accuracy, so that the upper and smaller I end of thebobbin shall come about the eighth of an inch from the point of the spindle, .andfor effecting this purpose various modes of packing have been heretofore tried with only partial success. The common mode of packing is for the operator to stuif in a piece of the roving around 'the spindle, between the bottom of the bobbin and the bearing of the spindle, but this is a very troublesome and wasteful method, as this pecking has to be Jeplaced every time the bobbin is set on the spindle. I

Before unwinding a cop from a bobbin, it is-necessary to steam it, to take the kinks out of the fibrcof the yarn, and therefore any packing connected with the bobbin must be of such a nature that neither the bobbin nor the'packing shall be affected by the moisture of tbe steam to injure or dcrange it. My invention is designed to accomplish this object, and does so effectually, by introducing a packing into the ordinary bobbin without necessitating any change in its construction, in such a manner that its central hearings on the spindle remain the same after the bobbin has been steamed, thus giving a permanent character to the packing;

- A represents a spindle, on which is placed a bobbin,B, in the position required for spinning, the upper end of'the bobbin being set about one-eighth of an inch below the point of the spindle, where it must be held fixedly in a central position on the spindle, during the operation of spinning, by means of packing of some'lrind. For this purpose, I bore three or more holes, a a a, of about the eighth of an inch in diameter, through-the bobbin obliquely, in the same angle to its axis, as shown at fig. 2, and at equidistant points in the sides, as'shown at fig. 3, so that the holes shall each pass partly through the tube or bore, 12, of the bobbin, and intersect the plane of a transverse section at points exactly equidistant from th'e centre of the bobbin, as shown at fig. 4. In the holes a. a a I inserta packing, formed of a piece of twine, rubb'er, or-other suitable substancc, to fill them well, passing it continuously through them from one to another, and cutting 01? the ends of the packing on the outside where they come out of two contiguous holes. The wood between the two contiguous holes is cut away, to form a little groove for receiving the twine in its passage from one hole to the other, so that the strand of the twine or substance of the packing shall be flush or even with the outside of the bobbin, as shown in fig. 2." I It will be observed, also, that when the packingis in the holes, the substance of it will project equally into the tube or bore of the bobbin, so that, when the bobbin is placed upon a spindle, the parts thus projecting will bear upon its sides uniformly, and secure the bobbin on-the spindle firmly in a central position. The holes may be bored in any part of the bobbin, or atany angle of inclination.

Having thus described my invention, and the mode by which it is carried intopraotical efiect, what I claim as new, and desire to secure by Letters Patent, is-- I i Packing bobbins by boring holes through them obliquely to the line of their axis, in such a manner that the holcsshall intersect the plane of a transverse section of a bobbin at points equidistant from its centre, and inserting therein twine, rubber, or other equivalent packing, substantially as :ind'for the purposes herein shown and described.
